Inventor: KATOU HITOSHI
IPC: G03F7/039
Filed: 1981-03-31
Abstract: PURPOSE:To obtain a sensitized positive type radiation-sensitive polymer material of high sensitivity, by adding tetraalkyl ammonium perchlorate to said  material. CONSTITUTION:Tetraalkyl ammonium perchlorate is added as a sensitizer to a positive type radiation-sensitive polymer material. As said material, polymethyl methacrylate (PMMA), a copolymer of methyl methacrylate and methacrylic acid, etc. are used, and the weight average molecular weight of PMMA to be used is within 500-10,000 thousand.
